"APPARATUS AND SYSTEM TO DEFINE A DIRECTION OF ACCESS TO A SUB-SURFACE TARGET, AND PROCESSES TO DETERMINE A PATH TO A SUB-SURFACE TARGET TO SELECT A DESIRED LOCATION FROM A SUB-SURFACE TARGET, AND TO POSITION AN APPLICATION TO DETERMINE A DIRECTION OF ACCESS TO A SUB-SURFACE TARGET OF AN IMAGE FORMING MACHINE ". A target device defines a direction of approach to a subsurface target under the guidance of imaging equipment such as a CT scanner or magnetic resonance imaging machine. The target device is positioned in relation to the target in such a way that the optional access direction, avoiding vital internal structures, can be selected by reference to the images displayed on the imaging equipment. The device projects a beam of visible light, such as a laser beam, into a region of a patient, indicating the entry point and the angle of access to the sub-surface target.
